The Features & Benefits of Perspex Acrylic Secondary Double Glazing

  • Our acrylic secondary Double Glazing is far less expensive/cheaper than glass secondary double glazing as it is generally a simple DIY installation.
  • Perspex is much lighter in weight than glass and will not shatter like glass.
  • Perspex acrylic is fairly flexible, allowing you to achieve an airtight perimeter, even on a fairly uneven wooden window frame.
  • Perspex secondary double glazing retains the outside appearance of your property – particularly useful if you live in a conservation area or a listed property.
  • Perspex secondary double glazing is 96% optically clear. As such, it is actually clearer than glass, and will allow more light into your room than conventional glass double glazing.
  • Perspex secondary double glazing is guaranteed for 10 years against UV degradation. Premium acrylic does not discolor with age.
  • Secondary double glazing provides for excellent thermal insulation. You no longer have to put up with the drafts from an old
  • Georgian sash, wooden, or crittal window. You don’t need to feel the cold from single glazed windows in the winter. Our secondary double glazing will inexpensively help to prevent those draughts and provide a thermal barrier.
  • If you live near a busy road or noisy neighborhood, secondary double glazing provides for great sound/acoustic insulation. It won’t completely stop the noise, but it will certainly help to reduce it.
  • Added Security. A would be intruder will find it harder to quietly get through two panes of window rather than one.
  • Helps reduce condensation
  • Widely used and approved by Building Preservation Specialists

Inexpensive DIY installation – How?

  • We can supply you the exact sized window panels that you need. You do not have to buy complete sheets of 8 feet x 4 feet Perspex acrylic. We do that , and then cut to the sheet to the sizes that you need. You only pay for what you need, not complete sheets. No waste.
  • Generally we supply 3mm clear acrylic as standard for secondary double glazing, but if budgets are tight, we can also supply a basic 2mm clear panel. 2mm thick secondary glazing panels work just as well but aren’t quite as rigid.
  • No wasted time. If you’ve ever cut acrylic with a jigsaw, you will know that its not the easiest job in the world to do. We will cut your secondary double glazing panels to your exact size requirements, free of charge.
  • ‘Magnafix (r)’. Magnafix is our registered fixing system that makes fitting of acrylic secondary double glazing very easy. Manafix is a two part tape system. One part is self adhesive white coloured steel tape. The other part is self adhesive magnetic tape. Most customers prefer to mount the white steel tape to their window frame (as it blends in with the white glossed wooden frame) and then the magnetic tape to the outer edge of the acrylic Perspex panel.
  • Once the magnetised Perspex acrylic secondary double glazing panel is offered up to the window frame, it gently pulls to the steel tape on the window frame and remains firmly in place for the rest of the winter. When you want to spring clean the windows, simply pull the Perspex acrylic from the window frame. If you choose to store your panels away form the window frame during the summer, all that remains visible of the original ‘magnafix’ is the white steel tape on the frame.
  • So, a simple, inexpensive, DIY installation.
